ANTIREFILLABLE BOTTLE.

Specification of Letters Patent.

Patented Oct. 28, 1913.

Application filed September 30, 1912. Serial No. 723,129.

To all whom it may concern A Be it known that we, J OHN GABRInLsoN and KNUT KARLsrRoM, subjects of the Kingof Sweden, residing at Buffalo, in the county of Erie and State of New York, have invent-- ed certain new and useful Improvements in Antirefillable Bottles, of which the following is a specification, reference being had therein to the accompanyingdrawing.

This invention relates to antirefillableb0ttles and the object of our invention is to furnish the neck or mouth of a bottle or other receptacle with. a novelcheck valve that does not interfere with the removal of liquid from the bottle, but prevents the bot tle from being filled after the check valve has been placed in position.

Our invention aims to eliminate thenefarious practice of unscrupulous merchants in refilling bottles that once contained a popular brand of liquid, with an inferior liquid, and dispensing the same as the original article. This practice is common among retail liquor dealers and druggists and by providing a bottle with our improved check valve, it is impossible for the bottle to be refilled.

Our invention will be hereinafter specifically described and then claimed and reference will now be had to the drawing, wherein Figure 1 is a vertical sectional view of a portion of a bottle provided with the check valve, Fig. 2 is a side elevation of a detached valve body, Fig. 3 is a top plan of the same, Fig. 4 is a bottom plan of a valve body, Fig. 5 is a side elevation of a detached valvular member, Fig. 6 is a front eleva tion of the same, Fig. 7 is a side elevation of a detached valve, Fig. 8 is a plan of the valvular member, and Figs. 9 and 10 are horizontal sectional views of the same.

Further describing our invention in detail with reference to the accompanying.

drawing, wherein like numerals denote corresponding parts throughout: 1 denotes a portion of a bottle or other receptacle having a neck 2 provided with a mouth or rim 3 of greater diameter than the neck 2, thereby forming an annular shoulder t within the mouth 3.

5 denotes a cylindrical valve body located within the neck 2 and having the outer end thereof provided with an annular flange 6 that is secured to the shoulder 4 by cement 7 or similar fastening means, whereby the valve-body 5 cannot be removed from the neck 2. 'The inner end of the valve body 5 is providedwith longitudinal equally spaced slots 8 in communication with radially dis posed openings 9. The valve body 5, adjacent to the openings 9 has a valve seat 10, and the inner end of said valve body is screw threaded, as at 11 to receive an end plate 12 that has a rectangular opening 13 establishing communication between the interior of the bottle and the interior of the valve body 5. The opening 13 also permits of a suitable instrument or key being insorted in the end plate to screw the same in the valve body.

14 denotes a double conical-shaped valve having an intermediate peripheral flange 15 thatnormally rests upon the valve seat 10 withthe inner end of the valve seated. The outer end of the valve 14 has a stem 16.

17 denotes a cylindrical valvular member mounted in the outer end of the valve body 5, the outer end of said member having a head 18 that rests upon the flange 6 of the valve body. The member 17 adjacent to the outer end thereof, has an annular groove 19 and in communication with said groove are angularly disposed ports 20 that establish communication between said groove and the mouth 3. The sides of the member 17, intermediate the ends thereof, are cut away, as at 21 and provided with a transverse opening 22. Arranged in this opening and secured therein by a plug 23 is a locking member having diametrically opposed resilient arms 24. These arms are adapted to engage an annular shoulder 25 provided therefor in the inner wall of the valve body 5. Said arms being easily snapped into position to hold a valvular member and prevent its withdrawal from the valve body 5. The sides of the valvular member have vertical slots 26 and the lower end of said valvular member is reduced and cupped, as at 27 to receive the stem 16 of the valve 14:. The slots 26 establish communication between the valve body 5 and the ports 20.

There is sulficient play or'movement between the valve 14 and the cupped end of the valvular member to permit of the valve 14' opening when the bottle 1 is tilted or inverted. The contents of the bottle can flow into the inner end of said valve body 5, through the valve seat 10, around the valvular member and through the ports 20 thereof, thus permitting of the contents of the bottle being removed. \Vhen the bottle is held in an upright position the valve 14: is seated by gravity, closing the valve seat 10 and preventing liquid that is poured into the mouth 3 from entering the bottle. The shape of the valvular member 17 prevents instruments from being inserted to raise the gravity seated valve 14, consequently the bottle cannot be successfully tampered with.

In practice, the valve body and the parts held thereby are made of aluminum or a metal not susceptible to a chemical action by the contents of the bottle.

What we claim is An anti-refillable bottle comprising the combination with a bottle neck, of a valve body arranged therein and provided intermediate its ends With a partition to constitute a valve seat, a vertically movable flanged stem valve mounted upon said seat, a valvular member fixed within the said valve body and cupped for the reception of the stem of said movable valve, and a plate secured within the inner end of the valve body and provided with a rectangular opening, that portionoflthe valve body below said partition provided with vertically disposed slots terminating in radially disposed recesses. y

In testimony whereof we aflix our signatures in the presence of two witnesses.
